Most buyers will have the property inspected by a licensed property inspector within the time frame that was agreed upon in the effective contract to purchase. Some buyers will have several different inspectors inspect the property, if they wish to obtain professional opinions from inspectors who specialize in a specific area (eg. roof, HVAC, structure). If the agreement is conditional upon financing, then the property will be appraised by a licensed appraiser to determine the value for the lending institution via third party. This is done so that the lending institution can confirm their investment in your property is accurate. A buyer of a commercial property may also have a complete environmental audit performed and/or soil test, if required by the lending institution.
Either a title company or an attorney will be selected as the closing agent, whose job is to examine and insure clear title to real estate. After researching the complete recorded history of your property, they will certify that 1) your title is free and clear of encumbrances (eg. mortgages, leases, or restrictions, liens) by the date of closing; and 2) all new encumbrances are duly included in the title.
